Abstract: Compositions and methods for grinding inorganic particles, such as cement, cement clinker, limestone, or other inorganic particles, involving a grinding efficiency enhancing additive comprising a crude glycerin byproduct, obtained through the use of heterogeneous catalyst processes in biodiesel fuel production. The molecules generated through the use of such heterogeneous catalytic processes result in a crude glycerin that confers good additive formulation stability, while avoiding or minimizing large quantities of undesirable compounds such as fatty acids, fatty acid esters, and salts.
